Microsoft 365 Management &
Co-Management for Enterprises
Your Microsoft tenant is the operating system of your business. We run it — or run it with you — so your team stays focused on revenue, and your auditors stay out of your inbox. M365 A&S Specialist. Copilot Ready Partner.
Co-Managed or Fully Managed
Your internal capacity, your compliance obligations, and your growth trajectory determine the right model. Most clients start with a tenant assessment, and we scope from there.
Co-Managed M365
Your internal team keeps admin access and owns day-to-day operations. ICS provides architecture, escalation, security engineering, and after-hours coverage. Ideal for organizations with 1–3 internal IT staff who need senior Microsoft depth on call.
Fully Managed M365
ICS owns the tenant end-to-end — provisioning, licensing, security baselines, patching, user lifecycle, incident response. Your team stays focused on the business. Ideal for organizations without a dedicated Microsoft administrator.
The Full Microsoft 365 Stack
Every layer of the tenant — from licensing through Copilot — owned, measured, and reported on monthly.
Licensing & Tenant Administration
E3/E5/Business Premium/Copilot license optimization, tenant hardening, domain + DNS, billing reconciliation, and continuous license utilization audits. Savings identified in most first-90-day engagements.
Identity & Access (Entra ID)
Entra ID tenant hardening, Conditional Access, MFA enforcement, privileged identity management (PIM), guest/B2B governance, and SSO for line-of-business apps.
Endpoint Management (Intune)
Microsoft Intune co-management or greenfield deployment, Autopilot provisioning, Windows/macOS/iOS/Android policy, app deployment, and hybrid Entra join for on-prem environments.
Exchange Online & Teams
Mail flow, shared mailbox governance, Teams policy, meeting/calling, Teams Rooms deployment, and Direct Routing. Includes migration from on-prem Exchange or Google Workspace.
SharePoint & OneDrive Governance
Information architecture, sensitivity labels, DLP, external sharing controls, retention policies, and Copilot-ready permissions remediation — so Copilot doesn't surface content it shouldn't.
Microsoft Security Stack
Defender for Office 365, Defender for Endpoint, Defender for Cloud Apps, and Microsoft Sentinel SIEM. Deployment, tuning, 24×5 monitored operations, and quarterly posture reviews.
Copilot Readiness & Rollout
SharePoint permissions remediation, sensitivity labels, license fit, pilot design, change management, and adoption measurement. Copilot Ready Partner designation.
Compliance & Audit Support
Microsoft Purview configuration, evidence packaging for SOC 2 / HIPAA / GLBA / PCI DSS audits, Vanta-integrated continuous monitoring, and regulator-ready documentation.
From Tenant Audit to Managed Operations
Predictable 8-week path from first conversation to fully operational managed tenant. Every gate has a written deliverable so you know what you're getting.
Tenant Assessment
Fixed-fee tenant operations assessment — licensing audit, security baseline, identity posture, Exchange/Teams/SharePoint governance review, and prioritized remediation roadmap.
Stabilize
Close the highest-severity gaps — Conditional Access, MFA coverage, privileged access, backup, license cleanup. You get a stable baseline before we take ongoing ownership.
Transition to Managed Operations
Runbook handoff, monitoring integration, ticket routing, escalation paths, and first monthly business review scheduled. From here, co-managed or fully managed, depending on your model.
Ongoing Operations + QBRs
Daily operations, monthly reporting, quarterly business reviews against defined SLAs and roadmap, and annual license + security posture optimization.
Scoped Engagements. Monthly Retainers. No Surprises.
Tenant assessments and onboarding are fixed-fee with written deliverables. Ongoing co-managed and fully managed operations run on a monthly retainer scoped to your user count, security posture, and workload complexity. Every proposal is written, reviewed with you, and signed before work starts.
The Broader Microsoft Practice
M365 Management is one piece of the ICS Microsoft practice. Explore adjacent capabilities that often accompany a managed tenant engagement.
Microsoft 365 Licensing
Licensing estate audits, E3 vs E5 vs Business Premium modeling, Copilot pilot sizing, CSP transitions, and quarterly governance — paired with managed operations so licensing tracks actual tenant usage.

Do you offer co-managed Microsoft 365 services or only fully outsourced admin?+
Both. Co-managed is our most common engagement — your internal team keeps admin rights and owns daily operations, and ICS provides architecture depth, escalation, security engineering, and after-hours coverage. Fully outsourced is available for organizations without a dedicated M365 administrator. We scope the right model during the tenant assessment.
What is the M365 A&S Specialist designation?+
Microsoft 365 Administration & Support Specialist is a Microsoft partner-level recognition that reflects demonstrated depth in M365 lifecycle management, security, and compliance. ICS has held this designation since its introduction and regularly renews it against Microsoft's current technical and customer-evidence requirements.
How do you handle identity and Entra ID tenant hardening?+
Every engagement starts with an Entra ID posture review — Conditional Access coverage, MFA enforcement, privileged identity management (PIM), legacy authentication, break-glass accounts, and guest/B2B governance. We have a fixed-scope Entra ID Tenant Hardening accelerator for organizations that want to close identity gaps before moving to ongoing managed operations.
Can you help us prepare for Microsoft 365 Copilot?+
Yes. ICS is a Copilot Ready Partner. Copilot rollout requires SharePoint permissions remediation, sensitivity labels, license fit analysis, and change management — all of which are part of our M365 management practice. We handle readiness, pilot, and full rollout with adoption measurement.
How do you price ongoing Microsoft 365 management?+
Onboarding and assessment engagements are fixed-fee with defined deliverables. Ongoing co-managed and fully managed operations are scoped as a monthly retainer based on user count, security posture, and workload complexity. Every proposal is written — no open-ended time-and-materials for transformation work.
Do you work with organizations outside of Dallas?+
Yes. ICS serves clients across North America and 5+ countries from our Dallas headquarters. Our delivery team operates 24×5. For Dallas-Fort Worth clients specifically, we also offer on-site support — see our Dallas M365 management page.
Will you work with our existing Microsoft partner or CSP?+
Often yes, though it depends on your scope. We frequently partner alongside CSPs that handle licensing only, providing the administration, security, and compliance depth they don't. If you want ICS to own licensing end-to-end, we can become your CSP of record — no transition fees.
How long does onboarding take?+
Tenant assessment runs 2 weeks. Stabilization phase runs 3–6 weeks depending on gap severity. Full transition to managed operations typically completes inside 8 weeks — with critical security gaps closed well before that.
Ready for a Microsoft 365 You Don't Have to Worry About?
